NEC Phone System DT820 - 6

With the DT820 telephones, we are providing a better way to upgrade your phones in the field, with software upgradability. Through licensing, the DT820 6-button and 8-button self-labeling models are able to upgrade their network support from 10/100 to 10/100/1000. And on the 8- button self-labeling, you can increase the line presence from 8 to 16 to 32. No longer is there any need to stock or purchase new hardware.
